HOT-AIR REGISTER.

.SPECIFIGATION forming part of Letters Patent N 0. 718,446, datedJanuary 13, 1903. Application filed March 5, 1902. Serial No. 96,764.(No model.)

To ail whom it may concern:

Be it known that I, CHARLES H. FOSTER, a citizen of the United States,residing at Omaha, in the county of Douglas and State of Nebraska, haveinvented a certain new and useful Hot-Air Register, of which thefollowing is such a full, clear, and exact description as will enableany one skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, forming part ofthis specification.

My invention relates to hot-air registers, and more particularly to thatclass of registers known as side-wall registers, which are placed in avertical position in or against the side wall of a room instead of beingplaced in a horizontal position in the floor.

My invention consists in various novel features and details ofconstruction, which are fully described in the following specificationand pointed out in the claims affixed thereto.

In the accompanying drawings,which illustrate one form of register madein accordance with my invention, Figure 1 is a front elevation, on aslightly-reduced scale, the valve being shown closed. Fig. 2 is avertical section through a portion of the frame of the register. Fig. 3is an end view of the grille. Fig. 4 is a detail view showing a portionof the valve. Fig. 5 is a vertical section of the complete reg ister,together with a portion of the wall to which the same is attached, thevalve being shown partially open. Fig. 6 is a rear view of a portion ofthe register, the valve being closed. Fig. 7 is a view similar to Fig.6, but showing the valve open. Fig. 8 is an enlarged sectional viewshowing a detail of construe tion, and Fig. 9 is an enlarged elevationshowing a detail of construction.

Like marks of reference refer to similar parts in the several views ofthe drawings.

10 represents the border of the register, which is preferably made ofcast metal. The border 10 is preferably curved, as shown in Figs. 2 and5, so as to form a rearwardly-extending flange adapted to seat againstthe wall. This flange is preferably provided with a flattened portion11, so as to give a greater bearing-surface against the wall.

In Fig. 5, 12 represents the base-board of the wall, against which theflattened portion 11 rests.

13 represents the plaster, and 14 the lathing, of the wall.

The frame 10 is preferably held against the wall by means of screwspassing through lugs 15, Fig. 1, formed on the flattened portion 11 ofthe frame. Formed in the frame 10 is a valve-opening 16, preferablyrectangular in form. Fitting in the valve-opening 16 is a valve 17,preferably made of thin sheet-steel. The valve 17 is provided with beads18 and 19 adjacent to its edges to strengthen it, and it may also bestamped or otherwise ornamented, as shown in Fig. 1, to add to itsappearance and also to strengthen it. Carried by the sides of the frame10 are two inwardlyprojeoting bearing-arms 20, upon which the valve 17turns. In order to keep the valve 17 in position on the bearing-arms 20,I pro vide each of said arms with a semicircular bearing-post 21, whichpasses through a rectangular opening 22 in the valve 17.. Each of thebearing posts 21 is provided with a recess 23, which prevents the valve21 from being disengaged from the said post except when in oneparticular position, as will be hereinafter described.

25 is a grille, which is adapted to act as a foot-rest when the valve isin its open position. The grille 25 is fitted to the valve 17, as willbe described. Near the upper edge of the valve 17 are formed threeopenings 26, similar to the one shown in Fig. 4. Formedon the grille 25are three corresponding pivot-lugs 27, which are adapted to fit theopenings 26. On the two end lugs 27 I form slightly-projecting points28. When it is desired to as semble the parts of the register, I passthese pivot-lugs 27 through the openings 26. As the end lugs 27 passthrough the openings 26 the points 28 will force their way through thethin sheet-steel, bending up a bur as they pass through the openings.After they are in position I bend this bur down, and thus prevent thelugs from passing back through the openings. Carried by the side of theframe 10 are brackets 30, each of which is provided with arearwardly-facing recess 31 and a guide-lug 32. The recesses 31 areadapted to engage with stops 33, Fig. 3, at the rear end of the grille25 when the valve is in its open position, thus limiting the movement ofthe valve and the grille. The grille 25 is provided with curvedguideways 3a, which ride on the guide-lugs 32. On account of the curvedform of these guides 34: the valve 17 can be adjusted in any suitableposition, the friction of the guide upon the lug being sufficient tohold the valve in the required position.

Within the flange 10 and surrounding the valve-opening 16 I form in theborder 10 a groove 36, which is adapted to receive the edges of theflue-pipe 37. In order to make a tight joint between the pipe and theregister, I prefer to fill this groove 36 with cement 38, as shown inFig. 5, before inserting the edges of the flue-pipe. By means of thisconstruction I not only provide a simple and efficient means for makinga tight joint between the register and the flue-pipe, but I am alsoenabled to utilize the lath-and-plaster space and also the base-boardspace for the fluepipe, as the front side of the flue-pipe can pass downin front of the joining-line of the register and base-board, as isclearly apparent from Fig. 5 of the drawings.

The operation of my register is so simple as to scarcely need specialexplanation. \Vhen it is desired to open the register, the lower end ofthe valve 17 is forced inwardly. As the lower end moves inwardly theupper end will move outwardly, the curved guides 32L of the grille 25riding on the guide-lugs 32. When the valve is completely open, thestops 33 will come into engagement with the recesses 31 of the brackets30, and thus positively stop the movement of the valve and grille, sothat the grille may be used as a footrest. hen it is desired todisconnect the valve from the pivot-posts 21, the grille 25 is raised,so that the stops 33 will pass above the brackets 30. The grille can benow brought completely in front of the frame 10 and the valve 17 tippeduntil it becomes disengaged from the pivot-posts.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is-

1. In a hot-air register, the combination with a frame, of a sheet-metalvalve pivoted therein and provided with an opening, a grille providedwith a pivot-lug adapted to fit the opening in said valve,and aprojection formed on said lug to prevent its return through saidopening.

2. In a hot-air register, the combination with a frame provided with aguide-lug, of a valve pivoted in said frame, a grille pivoted to saidvalve, and a curved guide carried by said grille and riding on said lug.

3. In a hot-air register, the combination with a frame, of aninwardly-projecting arm carried by said frame, a recessed semicircularpivot-post carried by said arm, and a valve provided with an openingembracing said pivot-post and engaging with both the recess and theconvex face of said pivot-post.

4:. In a hot-air register, the combination with a frame, of aninwardly-projecting arm carried on the side of said frame, a recessedsemicircular pivot'post carried by said arm, and a valve provided withan opening embracing said post and engaging with both the recess and theconvex face of said pivot-post.

5. In a hot-air register, the combination with a frame provided with avalve-opening, of a rearwardly-extending flange surrounding three sidesof said frame, the fourth side being left open, and a flue-boxprojecting through said open side, said frame being provided with agroove surrounding said valveopening for receiving the edges of saidfluebox.

('3. In a hot-air register, the combination with a frame provided with avalve-opening, of a single rearwardly-projecting flange carried by saidframe and adapted to contact with the wall, and a flue-pipe projectingbeyond the point of contact of said flange with said wall and joiningsaid frame.

In testimony whereof I have hereunto set my hand and affixed my seal inthe presence of the two subscribing witnesses.

CHARLES H. FOSTER.
